Objective To evaluate the value of a nomogram model based on ultrasonographic features and inflammatory indicators in the preoperative noninvasive prediction of pathological grading of urothelial carcinoma of bladder(UCB).Methods A retrospective analysis was conducted on 471 patients with pathologically confirmed UCB,and the patients were assigned to high-grade group(401 cases)or low-grade group(70 cases).Basic clinical data(gender,age,macroscopic hematuria),ultrasonographic features(lesion location,blood flow signal,etc.),and blood inflammatory indicators(e.g.neutrophil-to-lymphocyte ratio[NLR])were collected.Independent predictors were screened using univariate and multivariate logistic regression,and a nomogram model was constructed.Model performance was evaluated using the receiver operating characteristic(ROC)curve,calibration curve,and decision curve analysis(DCA).Results Multivariate logistic analysis identified gender(odds ratio[OR]=2.68),age(OR=1.08),macroscopic hematuria(OR=3.19),lesion located in the trigone(OR=4.59),positive blood flow signal(OR=2.87),and NLR(OR=1.03)were independent predictors of high-grade UCB(all P＜0.05).The combined model(clinical features+ultrasonographic characteristics+inflammatory indicators)achieved an area under curve(AUC)of 0.892,which was significantly higher than the clinical feature-only model(AUC=0.799)and the clinical+ultrasonographic model(AUC=0.856).The calibration curve demonstrated good consistency between predicted and actual outcomes,and DCA confirmed its optimal clinical net benefit.Conclusion The nomogram model integrating clinical features,ultrasonographic characteristics,and inflammatory indicators can effectively discriminate UCB pathological grading,providing a reliable preoperative noninvasive assessment tool for personalized treatment decisions.

Objective To investigate the efficacy of extracorporeal shock wave therapy(ESWT)combined with ultrasound-guided corticosteroid injection(CSI)for the treatment of primary frozen shoulder(PFS).Methods Ninety-nine patients with PFS who visited the pain department of the Affiliated Hospital of Xuzhou Medical University between April 2024 and July 2024 were enrolled and randomly divided into three groups according to the randomized number table method:ESWT group(T group),CSI group(I group),and combined treatment group(TI group),with 33 patients in each group.Visual analogue scale(VAS)scores,shoulder range of motion(SROM),and Constant-Murley shoulder scores(CMS)were recorded before treatment and at 1,4,8,and 12 weeks post-treatment.Additionally,the patients'Ascens Insomnia Scale(AIS)scores were recorded before treatment and 1 month after treatment.The occurrence of adverse effects and the use of remedial medications during the treatment period were also documented.Results Compared with pre-treatment,VAS scores decreased,and SROM and CM scores improved at all time points after treatment in all three groups(P<0.05).AIS scores also decreased in all three groups at 1 month post-treatment(all P<0.05).Intergroup comparisons revealed that the TI group exhibited signifi-cantly lower VAS pain scores,greater SROM(forward flexion and backward extension),and higher CM scores at 4,8,and 12 weeks post-treatment compared to the T and I groups(Bonferroni-corrected P<0.05).No statistically significant differences were observed between the T and I groups for these measures(Bonferroni-corrected P>0.05).Additionally,there were no statistically significant differences in AIS scores or adverse effects occurrence among the three groups at 1 month post-treatment(P>0.05).Conclusion The combined treatment demonstrated greater efficacy compared to trigger point extracorporeal shock wave therapy alone and periapical steroid injection alone,resulting in significant improvement in the patient's clinical symptoms and quality of life.

Objective:To explore the teaching reform of the Food Analysis experiment course under the concept of employment-oriented education,and to improve students'practical ability and employment competitiveness.Methods:Taking students majoring in Food Quality and Safety at a certain university as the research objects,the control group adopted traditional teaching,while the experimental group carried out reforms by optimizing the curriculum system,innovating the teaching mode,and establishing a diversified evaluation system.The total scores,teaching effectiveness,satisfaction with the teaching mode,and the evaluation of graduates by employers between the two groups were compared.Results:The average total score of the experimental group was significantly higher than that of the control group(P＜0.05).The teaching effect evaluations of the experimental group in improving experimental operation skills and enhancing employment position cognition were all higher than those of the control group(P＜0.05).The satisfaction of the experimental group with the teaching mode was better than that of the control group(P＜0.05).In the evaluation results of employers on graduates,the excellent rate of the experimental group was significantly higher than that of the control group(P＜0.01).Conclusion:The reform measures effectively improve the teaching quality and students'comprehensive literacy,and deliver high-quality talents with both practical ability and innovative thinking to the food industry.

In modern society, sugary foods have become an integral part of many people′s lives. However, excessive sugar consumption has adverse effects on both overall health and oral health, serving as a contributing factor to the global increasing incidence in oral diseases, cardiovascular diseases, cancers, obesity, and diabetes. In response to the health risks related to high-sugar diets, the World Health Organization (WHO) and World Dental Federation (FDI) have proposed initiatives and recommendations, with various governments implementing different policies and strategies to reduce sugar intake. Chinese government has also taken proactive measures. The "Healthy China Action (2019-2030)" initiative introduced by the State Council in 2019 established a crucial benchmark in limiting the average daily intake of added sugar to 25 g per person forward to 2030. Experts from Chinese Center for Disease Control and Prevention and the field of oral health have meticulously examined the impacts of sugar reduction on oral health, as well as strategies, methods, and practical considerations related to reducing sugar intake through several meeting and wrote the "Expert consensus: reducing free-sugar for caries prevention", which was subsequently reviewed and revised based on the feedback from multiple stakeholders. They have conducted thorough analyses of global trends in sugar reduction and best practices to provide valuable insights to China for crafting effective policies and strategies on sugar reduction. This consensus mainly includes the classification of free sugars, the latest scientific evidence on dental caries, recommendations from WHO on sugar-sweetened beverage taxes, nutrition labeling, advertising, food reform, adjusting supply systems, education, and promotion strategies, as well as sugar reduction actions taken by various governments around the world. Combining the actual situation in China, policy recommendations and authoritative popular science knowledge on sugar reduction for caries prevention to public are proposed to advocate for experts in multiple fields to focus on sugar reduction for caries prevention, promote the work process, and provide the scientific basis for oral health educators.

Objective:To investigate the role of aging-related genes(ARGs)in the prognosis of lung squamous cell carcinoma(LUSC)and establish a novel prognostic prediction model.Methods:Transcriptomic data and clinical information of LUSC patients were obtained from TCGA,combined with ARGs from Aging Atlas.Key genes were screened through differential expression analysis,survival analysis,and Cox regression to construct a prognostic model.Model performance was validated in clinical subgroups,and biological pathway enrichment(GSEA)and immune microenvironment analyses were performed.Results:Five ARGs(ERFFI1,MDH1,SENP2,SNAI1,TP63)were identified to build the model.Significant survival differences were observed between high-and low-risk groups(P＜0.001),with 1-,3-,and 5-year AUC values of 0.610,0.668,and 0.665,respectively.The risk score was an independent prognostic factor(HR=11.261,95％CI:3.654-34.701,P＜0.001)and showed predictive efficacy in both early-stage(Ⅰ-Ⅱ,P=0.022)and advanced-stage(Ⅲ-Ⅳ,P=0.004)patients.GSEA revealed significant enrichment of Alzheimer's disease(P=0.003)and cell adhesion pathways(P=0.008)in high-risk groups.SNAI1 correlated positively with M1/M2 macrophage infiltration(r=0.45,P＜0.001),MDH1 associated with 12 immune cell types(|r|＞0.3,P＜0.05),and the risk score linked to CD8+T cells(r=0.38)and M2 macrophages(r=0.32)(both P＜0.001).Twenty-three immune checkpoints(e.g.,TNFRSF14,CD200R1)were differentially expressed between groups and survival-related(P＜0.05).High-risk patients exhibited elevated TIDE scores(P＜0.001),indicating enhanced immune suppression.Conclusion:This model provides a novel tool for LUSC prognosis assessment,but further clinical validation is required.

Objective To analyze the influencing factors of diabetes insipidus after pituitary tumor surgery,thereby providing evidence for enhancing perioperative management of pituitary tumor surgery and preventing diabetes insipidus after pituitary tumor surgery.Methods The clinical data of patients who underwent pituitary tumor surgery in our hospital from January 2014 to December 2024 were retrospectively analyzed.The relationship between each variable and postoperative diabetes insipidus was explored through univariate analysis,and multi-variate regression analysis was used to identify the independent risk factors for the occurrence of postoperative diabetes insipidus.Results Univariate analysis showed that the occurrence of diabetes insipidus after pituitary tumor surgery was related to tumor invasiveness,tumor growth direction,surgical resection degree,surgical time and surgical method(P<0.05).Logistic regression analysis showed that the surgical time>4 hours(P=0.001)and tumor growth breaking through diaphragma sellae(P=0.004)were independent risk factors for the occurrence of postoperative diabetes insipidus.Conclusion The surgical time and tumor growth direction are closely related to diabetes insipidus after pituitary tumor surgery;therefore,in order to reduce the incidence of diabetes insipidus after pituitary tumor surgery,a thorough evaluation should be conducted preoperatively to clarify the direction of tumor growth;minimally invasive surgery should be adopted as much as possible during the operation and the skills of surgeons should be improved to shorten the surgical time;and close observation should performed after surgery.
